.... And it was then when Harry woke up and realized all of it had just been a very long dream and he was still his 11 year old self living under the stairs.....

That would be interesting...

Actually, the best ending would be to have Harry killed off..

Maybe Ron.... too...

(Don't get me wrong, I love both Harry and Ron)

If it is the Disney-like 'happily-ever-after' ending, I don't think I would appreciate the HP books as much as I do now... (I think we all get enough of the happily-ever-after stuff from Disney alone.)

Even if Harry doesn't die, it should be a somewhat bitter and dark ending....

Something like the ending of LOTR...

They achieve their goal, yet LOTR is not 'just' an epic of the Fellowship of the Ring and Frodo..
